AP Physics 1 Exam: Format, Length, Dates and How to Prepare for 2027

The AP Physics 1 exam takes 3 hours. It has 42 multiple-choice questions and 4 free-response questions, and each section counts for half of your score. In 2027 it is on Wednesday 5 May, in Session 2.

This guide covers the whole exam in one place. You’ll see the format, the timing, the units and their weights, the four free-response types, how scoring works, and what changed for 2027. Then we get practical: how to spend your minutes, how to prepare in the last 12 weeks, and what to do on exam day.

Quick answer: what is the AP Physics 1 exam?

Quick answer: The AP Physics 1 exam is a 3-hour, algebra-based test of mechanics. Section I has 42 multiple-choice questions in 85 minutes (50% of your score). Section II has 4 free-response questions in 95 minutes (the other 50%). You can use a calculator, and a reference sheet is provided. The 2027 exam is on Wednesday 5 May 2027 in Session 2, and it is a hybrid digital exam: you read questions in the Bluebook app and handwrite your free-response answers.

Here is the exam at a glance.

All of these details come from the College Board’s AP Central and AP Students pages for the 2027 exam.

How long is the AP Physics 1 exam?

The AP Physics 1 exam lasts 3 hours in total. That is 85 minutes for the multiple-choice section and 95 minutes for the free-response section, which adds up to 180 minutes.

Your school will confirm the exact start time and the break between sections, because they depend on your test centre. Plan to be in your seat well before the start, since check-in takes time.

Here is what the timing means for each question.

Two minutes per multiple-choice question sounds tight, but it is fair. Many questions take under a minute. A few sets built on one graph or experiment take longer. If you bank time on the quick ones, you can spend it on the long ones.

When is the AP Physics 1 exam in 2027?

The 2027 AP Physics 1 exam is on Wednesday 5 May 2027, in Session 2. Session 2 is the second exam slot of the day, and your school confirms the exact start time.

One thing to check early: AP Physics C: Electricity and Magnetism is also on Wednesday 5 May, in the same Session 2. So you cannot sit both exams. If you want both, you will need to talk to your school coordinator well before registration closes. Physics C: Mechanics is on Monday 3 May in Session 1, so that one does not clash.

Your school sets its own deadline to sign up, usually in the autumn. The College Board’s 2027 exam fee is $99 in the US and $129 for students outside the US, with a reduced fee for students who qualify. Check your school’s AP coordinator page for the final amount and any late fees.

What changed in the AP Physics 1 exam for 2027?

For May 2027, the multiple-choice section grew by two questions and five minutes, and the free-response section lost five minutes. The content and skills did not change.

Here is the change in one table.

The College Board says these changes do not alter the course content, the skills tested or the topics. Think of it as a small rebalancing. You get a little more multiple choice and a little less writing time.

There was a much bigger change in 2025. Older study guides still describe the pre-2025 exam, so watch out for them.

If a website says the exam has 55 questions, it is out of date. The exam you will sit has 46 questions in total: 42 multiple choice plus 4 free response.

Is the AP Physics 1 exam digital?

Yes, but only partly. AP Physics 1 is a hybrid digital exam. You read the multiple-choice questions and answer them in the College Board’s Bluebook app. You also read the free-response questions in Bluebook. But you write your free-response answers by hand in a paper booklet, which is then sent for scoring.

This matters for how you practise. Physics free response needs diagrams, graphs and equations, and those are much easier on paper. So the College Board keeps handwriting for Section II.

Here is what to do about the digital part:

• 1. Install Bluebook early. Do it on the device you will use on exam day, and run the practice test the College Board provides.

• 2. Practise reading on a screen. Graphs and diagrams look different on a laptop than on paper. Get used to zooming and scrolling.

• 3. Practise handwriting under time. Write full free-response answers by hand, not just in your head.

• 4. Bring the allowed tools. Your school will tell you what to bring. Typically that is pencils, pens and an approved calculator.

Can you use a calculator on the AP Physics 1 exam?

Yes. Calculators are allowed on the whole AP Physics 1 exam, both sections. The College Board keeps a list of approved calculators and the exam-day rules in its AP calculator policy, so check your model against that list well before May.

A scientific calculator is enough. You do not need a graphing one. What you do need is a calculator you know well. Practise with the same one all year, and know how to switch between degrees and radians. Many lost marks come from a calculator left in the wrong angle mode.

Do you get an equation sheet?

Yes. The College Board provides reference information for AP Physics 1. It is printed and mailed to schools, and it is also available inside Bluebook during the test preview and on exam day.

The sheet lists many of the equations and constants, but it does not teach you how to use them. Your job is to know what each symbol means and when an equation applies. A good habit is to use the official sheet in every practice session from the start, so it feels familiar. You can find the sheet on the College Board’s page for reference information for specific AP exams.

What is on the multiple-choice section?

Section I has 42 questions and is worth 50% of your score. Some questions stand alone. Others come in sets that share one stimulus, such as a graph, a data table or a description of an experiment.

The questions are computer-scored, and you choose one answer from the options. The 2027 exam has no multi-select questions, which were removed in 2025.

The College Board publishes what share of the multiple-choice section each unit gets. This is the most useful table for planning your revision.

Look at what this table tells you. Units 2 and 3 together are worth 36% to 46% of the multiple-choice questions. So forces and energy deserve more of your time than oscillations or rotational energy.

What is on the free-response section?

Section II has 4 free-response questions in 95 minutes, and it is worth the other 50% of your score. Every question is a new type introduced in 2025. A teacher or trained AP Reader scores your handwritten answers with a rubric that gives partial credit.

The College Board lists four question types. Here is what each one means in plain English.

The College Board does not publish point values for each type on its exam page, so do not trust sites that claim exact numbers for 2027. What it does publish is how the free-response section is weighted by skill.

Read that again. Argumentation, which means explaining and justifying your answer in words, is the biggest slice. Maths comes second. That is why students who can solve every equation still lose marks: they never learned to write a clear physics explanation.

How is the AP Physics 1 exam scored?

Your two sections are combined into one composite score, and the College Board converts it to a final score from 1 to 5. Multiple choice and free response each count for 50%.

The conversion is not a fixed percentage. The College Board sets the cut points after each exam, using a process called standard setting. For the revised exam, it said the new cut scores would be set in summer 2025. It does not publish the raw-score cut-offs for each grade.

So be careful with any “score calculator” that claims to know the exact line for a 4 or a 5. It is a rough guess at best. Here is what a score means in the College Board’s own words.

A 3 is generally treated as passing. Many colleges look for a 4 or a 5 when they decide on credit or placement.

What do AP Physics 1 scores look like?

In 2026, 68% of students scored 3 or higher on AP Physics 1, and 19% scored a 5. This comes from the College Board’s published score distributions.

In 2025, 174,401 students took the exam and the average score was 3.12.

Notice the jump between 2024 and 2025. The share of students scoring 3 or higher went from 47.3% to 67.3%. That is the year the revised exam began and new cut scores were set. The College Board has not said the exam became easier. But if you compare your results with older pass rates, remember you are comparing two different exams. Use the 2025 and 2026 numbers as your guide. For a fuller look at difficulty, see the FAQ at the end of this guide.

What are the eight AP Physics 1 units?

AP Physics 1 has eight units, and all of them are mechanics. The course is algebra-based, so you do not need calculus. Here is a plain-English summary of each unit, with what the exam usually tests.

Unit 1: Kinematics

This is the study of motion without asking why things move. You’ll work with position, velocity and acceleration, and read motion graphs. Expect questions that give you a graph and ask for a slope or an area.

Unit 2: Force and Translational Dynamics

This unit covers Newton’s laws, free-body diagrams, friction, gravity and circular motion. It is the biggest unit on the exam. If you can draw a correct free-body diagram every time, you will pick up marks in many other units too.

Unit 3: Work, Energy, and Power

Here you learn how energy moves and changes form. Kinetic energy, potential energy, work and power all live here. Energy-conservation problems are often easier than force problems, so they are a good place to gain speed.

Unit 4: Linear Momentum

This unit covers momentum, impulse and collisions. You’ll decide whether a collision conserves energy, momentum or both. Many wrong answers come from mixing these ideas up.

Unit 5: Torque and Rotational Dynamics

Torque is the turning version of force. You’ll study balance, levers and spinning objects. Students find this unit new and tricky because the pictures look different from straight-line motion.

Unit 6: Energy and Momentum of Rotating Systems

This unit joins unit 5 to energy and momentum. It has a small weight on the multiple-choice section, 5% to 8%, but it shows up in free-response questions that connect several ideas.

Unit 7: Oscillations

This unit covers springs and pendulums. Since the 2025 revision it also includes the equations of motion for simple harmonic motion. It is a small unit, so do not spend weeks on it.

Unit 8: Fluids

Fluids moved into AP Physics 1 from AP Physics 2 in 2025. It covers pressure, density, buoyancy and flow. Because it is new, older practice papers will not have it. Use current College Board material for this unit.

If you are unsure whether to take Physics 1 or go straight to the next course, our guide on AP Physics 1 vs 2 vs C lays out the differences.

What skills does the AP Physics 1 exam really test?

The exam tests three groups of skills, which the College Board calls science practices. They are creating representations, mathematical routines, and scientific questioning and argumentation.

In everyday language:

• 1. Creating representations. Can you draw a free-body diagram, sketch a graph or build a model from a description?

• 2. Mathematical routines. Can you choose the right equation, set it up and solve it, with units?

• 3. Scientific questioning and argumentation. Can you explain why, and back it up with physics ideas?

Since the 2025 revision, any learning objective can be tested with any practice. So you can’t prepare by matching topics to question types. You need all three skills in every unit.

How should you pace the multiple-choice section?

Aim for about two minutes per question, and never get stuck. With 42 questions in 85 minutes, you have about 2 minutes each, but the time is uneven.

Here is a simple pacing plan:

• 1. First pass (about 60 minutes). Answer every question you can do in under 2 minutes. Mark the rest and move on.

• 2. Second pass (about 20 minutes). Go back to the marked questions. Eliminate options you know are wrong, then pick the best one.

• 3. Final check (about 5 minutes). Make sure every question has an answer. There is no penalty for guessing.

A few habits help:

• Read the stimulus first. In a set, the graph or table is the key. Spend 15 seconds on it before the first question.

• Estimate before you calculate. Ask “should the answer be bigger or smaller?” It catches many errors.

• Check units. If the units do not match, your equation is wrong.

• Watch the wording. Words like “net force”, “constant speed” and “just before” change the answer.

How should you tackle the free-response section?

Spend about 20 to 25 minutes on each question and start with the one you find easiest. With 4 questions in 95 minutes, you average about 24 minutes each, but the questions are not equal in difficulty.

Follow this method on every question:

• 1. Read the whole question. Parts build on each other. Part (b) often needs the answer from part (a).

• 2. Draw first. Sketch the situation. Add a free-body diagram or an energy bar chart if it fits.

• 3. Write the starting equation. Put the general equation down before you substitute numbers. Markers award marks for it.

• 4. Substitute with units. Show each step. A correct answer with no working may earn less.

• 5. Explain in full sentences. When it says “justify” or “explain”, name the physics law and say how it applies.

• 6. Do not erase. Cross out a wrong attempt with a single line. A partly correct crossed-out idea may still earn marks if you do not replace it.

For the experimental design question, practise a standard recipe. Name what you will change, what you will measure, what you will keep the same, and how you will use the data. Then say how you would show a relationship, often by graphing one quantity against another to get a straight line.

For the paragraph-style explanations in the qualitative/quantitative question, use a simple pattern: claim, evidence, reasoning. State what happens, point to the physics, then connect the two.

The most common mistakes on the AP Physics 1 exam

Most lost marks come from the same handful of habits. Here are the ones worth fixing first.

• 1. Skipping the diagram. Students try to solve in their heads. A free-body diagram turns a confusing problem into a list of forces.

• 2. Mixing up mass and weight. Mass is in kilograms. Weight is a force in newtons.

• 3. Using the wrong conservation law. Momentum is conserved in a collision without outside forces. Mechanical energy is conserved only when no energy is lost.

• 4. Writing vague explanations. “It speeds up because of force” earns little. “The net force is forward, so by Newton’s second law the acceleration is forward” earns marks.

• 5. Forgetting units and signs. A direction matters for velocity and force. A missing unit can cost a mark.

• 6. Ignoring the new Fluids unit. Older practice papers do not include it, so students never practise it.

• 7. Running out of time on one question. Move on and come back.

A 12-week plan for the AP Physics 1 exam

A steady plan beats a last-minute rush. This is Educifly’s own suggested plan, not an official College Board schedule. It assumes you start in early February and sit the exam on 5 May.

Plan on 3 to 5 hours a week outside class for most of this. These hours are a rough guide from our tutoring experience, and they vary a lot from student to student.

A weekly routine that works

Try this simple pattern each week:

• Two short sessions of 45 minutes each on the unit you are covering.

• One longer session of 60 to 90 minutes on mixed practice questions.

• One free-response question written by hand and checked against the scoring guidelines.

• Ten minutes at the end to list your mistakes and why they happened.

The mistake list is the secret. Students who track their errors fix them. Students who just do more questions often repeat the same mistakes.

Where to find official practice material

Use the College Board’s free material first, because it matches the real exam. Here is where to look:

• AP Classroom. Your teacher can open topic questions, progress checks and practice material.

• Bluebook practice tests. These let you rehearse the digital format.

• Past free-response questions. The College Board posts past free-response questions and scoring guidelines on AP Central. Note that questions from before 2025 follow the old format. They are still useful for physics skills, but the question types differ.

• The course and exam description. It is the official list of what can be tested.

When you use older papers, skip any waves questions, since waves are no longer in Physics 1. And remember that fluids will not appear in older papers at all.

What should you do in the week before the exam?

In the last week, stop learning new material. Focus on speed, accuracy and calm.

• 1. Do one last timed practice. Do it two or three days before, not the night before.

• 2. Reread your mistake list. This is better than rereading the textbook.

• 3. Review the equation sheet. Know where each equation sits.

• 4. Check your calculator. Fresh batteries, correct angle mode, on the approved list.

• 5. Test Bluebook. Log in, update the app and make sure your device is charged.

• 6. Pack the night before. Photo ID, pencils, pens and anything your school told you to bring.

• 7. Sleep. A rested brain beats an extra hour of cramming.

On the day, remember that the exam is long. Eat a proper meal, bring water if it is allowed, and take a breath at the start of each section.

Does a good AP Physics 1 score earn college credit?

It can, but the rules depend on the college. Each university decides what scores it accepts and what credit it gives. Many accept a 4 or 5 for a physics course or for general science credit. Some accept a 3. Some do not give credit for Physics 1 at all, especially for engineering and physics majors, who are often asked to take calculus-based physics instead.

The best step is to search “[college name] AP credit policy” for each college on your list. Most publish a table that shows the score needed and the credit awarded.

When should you get a tutor for the AP Physics 1 exam?

Consider a tutor when practice results stay flat even though you are working hard. That usually means a gap in understanding, not a lack of effort.

Signs that a tutor could help:

• You understand the lesson but get stuck on new problems.

• You lose marks on explanation questions in practice.

• You run out of time on timed papers.

• You are far behind a unit and the exam is close.

At Educifly, our AP Physics tutors work 1-on-1 online. Each student is matched with one tutor who stays the same every week, and sessions focus on free-response practice and error review. If you want to try it, you can book a free trial class. If you are also weighing Physics C, our guide to how hard AP Physics C is will help you decide. Taking other APs too?
